Rotating electrical machine and rotating apparatus

Abstract

This disclosure discloses a rotating electrical machine that is integrally formed with a reduction device having an input shaft and an output shaft and employs one of a field system and an armature as a rotor and the other of the field system and the armature as a stator, including a rotating shaft to which the rotor is fixed and that is coaxially connected to the input shaft of the reduction device, and a bearing support member configured to support bearings that rotatably support the input shaft of the reduction device, wherein the stator is provided to the bearing support member.

What is claimed is: 
     
       1. A rotating electrical machine that is integrally formed with a reduction device having an input shaft and an output shaft and employs one of a field system and an armature as a rotor and the other of the field system and the armature as a stator, comprising:
 a rotating shaft to which said rotor is fixed and that is coaxially connected to said input shaft of said reduction device; and 
 a bearing support member configured to support bearings that rotatably support said input shaft of said reduction device; wherein: 
 said stator is provided to said bearing support member, and 
 said bearing support member is provided so as to face a through-hole of a housing of said reduction device so that there is a gap between said bearing support member and said through-hole, said housing comprising said through-hole through which said input shaft is inserted, and being splittable in a direction orthogonal to an axial direction of said input shaft. 
 
     
     
       2. The rotating electrical machine according to  claim 1 , wherein:
 said bearing support member comprises:
 a support portion having a fitting portion to which said bearings are fit and having an outer diameter that is smaller than an inner diameter of said through-hole; and 
 a flange portion having an outer diameter that is larger than the inner diameter of said through-hole. 
 
 
     
     
       3. The rotating electrical machine according to  claim 1 , wherein:
 said bearing support member further comprises an inlaying and connecting portion that inlays in and connects to said stator. 
 
     
     
       4. The rotating electrical machine according to  claim 1 , further comprising:
 a yoke presser that is detachably connected to said rotating shaft and prevents a yoke of said rotor from shifting position in an axial direction of said rotating shaft. 
 
     
     
       5. The rotating electrical machine according to  claim 1 , further comprising:
 a motor electromagnetic portion having said rotor and said rotating shaft; and 
 a brake portion configured to brake a brake shaft connected to the side of said rotating shaft that is opposite to said reduction device, disposed adjacent to the side of said motor electromagnetic portion that is opposite to said reduction device; wherein: 
 said brake portion integrally comprises a yoke pressing portion that is detachably connected to said rotating shaft and prevents a yoke of said rotor from shifting position in an axial direction of said rotating shaft. 
 
     
     
       6. The rotating electrical machine according to  claim 5 , wherein:
 said brake shaft further integrally comprises a brake disk portion for braking said brake shaft. 
 
     
     
       7. The rotating electrical machine according to  claim 1 , wherein:
 said rotor comprises:
 a yoke that is fixed to an outer periphery of said rotating shaft; and 
 a magnet that is provided to said yoke, and wherein 
 
 said yoke integrally comprises a yoke pressing portion configured to prevent said yoke from shifting position in an axial direction of said rotating shaft. 
 
     
     
       8. The rotating electrical machine according to  claim 7 , further comprising:
 a motor electromagnetic portion having said rotor and said rotating shaft; and 
 a brake portion configured to brake a brake shaft portion connected to the side of said rotating shaft that is opposite to said reduction device, disposed adjacent to the side of said motor electromagnetic portion that is opposite to said reduction device, and wherein: 
 said yoke further integrally comprises said brake shaft portion. 
 
     
     
       9. The rotating electrical machine according to  claim 1 , further comprising a step portion against which said rotor butts, between said input shaft and said rotating shaft. 
     
     
       10. The rotating electrical machine according to  claim 2 , wherein:
 said bearing support member further comprises a step portion having a diameter smaller than a diameter of said fitting portion. 
 
     
     
       11. The rotating electrical machine according to  claim 1 , wherein:
 said bearing support member is configured to be mounted within said through-hole of said housing, and wherein said gap is provided between an outer circumferential surface of said bearing support member and an inner surface of said through-hole of said housing.
